What factors determine the use of electric door

Which factors determine the electric door of the use of the cycle of electric gate is generally used in factories, schools, residential areas, such as relatively dense place, to our life has brought a lot of convenience. However, the cost of electric door is very high, so we use the process to be reasonable and normal use, to extend the use of the cycle. Shanghai automatic door small series learned that the use of electric doors and many other aspects of the cycle has a close relationship, we come to understand the following.
Electric and non electric door slide door slide there is a big difference. Maintenance of automatic doors of the most simple way is the pulley design into a single form, the door body on one side by side hanging pulley on the slide rail, the formation of the pendant. The latter usually has two horizontal parallel slide and two (or four) pulley through the middle of the connecting piece and the suspension movement of the door body is connected, the electric door installation of the center of gravity of the movement of the door body just between the two track rail supporting force to form stable suspension and the stability of the structure can achieve good stability and the mute effect. But the slide rail of the electric door maintenance due consideration should be given to the door frame and a door body is fixed, hanging and adjusting, electrical components are installed and the exterior cover installation and other functions, the advantages of this design is installation and adjustment of the door body is convenient, and easy maintenance. However, there are many fatal weaknesses in this design.
From the mechanical structure, the basic components of the electric door is the guide rail, pulley and transmission belt. Because of this three part and the electric door operation is directly related to, electric door normal use conditions of wearing parts, the structure design, material, machining accuracy, installation and regulation determines the precision of the maintenance requirement and service life. The life span of electric door electric components is mainly related to improper use and incidental accidents.
First, because it is the lateral suspension structure, the door body to support are in a line, the door body center of gravity due to the installation of precision error and wind effects. The door body formed not only static side swing also produces dynamic side of the pendulum. To this end. This move door body at the lower part of the guide block, usually called a swing block, on the use of a bearing, bearing diameter less than lower portion of a door body guide groove, so that the door body in a two direction swing can still run. The vibration generated by the side of the side of the use effect on the performance of the noise, the consequences will inevitably lead to wear and tear of the pulley. Second, this side suspension structure makes the rail and the pulley in a completely open state, so it is bound to be easy to accumulate dirt, dust, so that the guide rail and pulley between the serious wear and tear. Therefore, the use of this electric door must pay attention to maintenance and maintenance. Third, the gap between the pulley and the guide rail is easy to slide, and the security of the use is not guaranteed. Therefore, the choice of this electric door must pay attention to the electric door of the wind pressure strength, fourth, this is not stable operation of the drive load changes, the electrical components of the service life of great influence.
The structural design of the electric door quality depending on the guide rail of aluminum alloy profile material, precision, strength, pulley material and machining precision, and the door body hanging pendant design and machining accuracy can effectively reduce installation error. Which can explain why Europe, especially Germany's similar electric door products more reliable. Because of the basic industries there, especially the average level of aluminum alloy processing is higher.
The structure of the electric door installation and commissioning is key to improve the precision, the guide rail straightness and the level of, parallelism and perpendicularity of the door body of the two suspension points formed by straight line and guide, maximize reduce static side of the door body pendulum. After the electric door is put into use, especially the initial stage, the door body is often adjusted to correct the errors caused by the operation. In addition, to strictly limit the weight of the door body, can not exceed the rated load of the electric door. Usually in the three months up to a year to conduct a comprehensive electric door cleaning and adjustment.
In order to solve the problem of side swing, the guide rail of the European high-grade electric door adopts the structure design of the vertical double guide rail. This structure not only effectively alleviate the dynamic side of the problem, but also to a certain extent, to solve the problem of the security of the door. More importantly, this structure greatly reduces the dynamic wear of the pulley. This point will be discussed in detail in the pulley section. The vertical double guide rail can strengthen the section curve according to the force condition of the door body, so that the weight of the door machine can be reached to 200 kg.
The life cycle of the electric door, and many other aspects of factors have a close relationship, the above-mentioned points is key factor determines the electric door using the time length, in addition, we should also be regularly for electric door maintenance and maintenance, to ensure the normal use.
